TANK OR RESERVOIR OF REINFORCED CONCRETE.

Specification of Letters Patent.`

original application sied Aprii 2, 1915, serial No. 18,661. Divided and this application sied october 17,

1917. Serial No. 197,135.

To all whom t may 'concer/n:

Be it known that I, WILLIAM Munsiin', a citizen of the United States, residing at 17 41 Clay avenue, city of New York, in the county of Bronx and State of 4New York, have invented certain new and useful Imforced'Concrete, of which the followingis a specification.

overcome the frictional resistance resulting from the weight of the wall on the bottom when the tank is being filled.

Ihave also provided a more efficient means `for reinforcing the wall, as will be hereini after described in detail.

`provements in Tanks or Reservoirs ofRein- In .the drawings, Figure 1 is a front elevation inminiature of a tank or reservoir em- Vvoirs adapted to contain w-ater and made'of Y reinforced concrete `and is divided out from my application, iledAprilv2, 1915, Serial In'an application for Letters Patent of the United States filed by Vme September bodying my invention; Fig. 2 is a vertical section through the lower portion of the wall and the corresponding adjacent portions o-f the bottom; Fig. 3 is atop plan view of1'a 'portion of the bottom with a portion "of its upper surface shown cut away to dis- 14th, 1911, andrecently allowed, I have `described a reinforced concrete tank for this may be considered an improvement on the invention described in that application.

Experience 4has developed. the 4fact that when a reservoir of this character has to be ing a constantly increasing cross-sectional built on sandy, gravelly or Vothersoil ofan f elastic or compressible nature, or when such soil lacks uniformity over its entire surface,

it will happen that after lling the freservoir to its maximum the weight of the. same, in addition-to the weight of the Huid contents, will cause a settlement of the bottom close the reinforcing members in two planes beneath the same; Fig. 4: is a vertical section of a portion of the bottom showing the radial reinforcing members arranged in groups of three.

In the drawings, 20 designates generally the bottom of the reservoir. In the form ,.illustrated, it is` shown as a comparatively flat disk having a relatively thin inner section 21 and arelatively thicker outer annular section 22 upon which the wall rests,

an yintermediate wedge shaped section 23 joining the inner and outer sections and havarea from the inner section outwardly. 'Ilie -Y press on the outer rim of the bottoni. The middle part of the bottom not being tlius under downwardpressure of the fluid'will tend to lift under the influence of the elasticity of the soil, while the weight ofthewall will keep the outer edge yof 'the `bottom f wie illustrated,` substantially plane and at its outer edge it is provided with an annular recess 24 having a bottom 25, upon which the wall rests, slopes downwardly and outwardlyto a flange 26 forming a gutter to collect overflowing water which is carried to the sewer by pipes 27. A depression 28 in the upper surface of the flange serves to carry ofi water, filling the gutter if the pipes 27 are clogged. Water is thus kept `away from the foundation of the structure.

`The reinforcing members of the bottom disk 'are arranged in two series. One coing crack the bottom, and one object fof thispresentsinvention is, to provide means for lessening this tendency orpreventing it.

In addition 'to' the means which I de f scribed for facilitating'the movement of the circular wall in the patent application referred to, I havefound it desirable to make a construction of the wall whereby its bottom where it contacts with the upper surface f f of the bottom' of' the tank shall be slightly 55,

inclined downwardly so' as tomore readily prises a series of radialbars arranged in three lengths, viz. one length 30 along the upper part of the inner section 21, another length 31 along the lower part of the section 23, and another length 32 along the lower part ofthe section 22. Circular bars 33 are arranged at` intervals transverse to the lengths 32. This series of bars is adapted to take care of the bending stresses produced in thebo'ttom and liable to crack the concrete. In Fig. I there is shown an arrangement in which this series ci bars is er CII ranged in groups of three, the middle the upper part of the disk, as shovambrain its lower par-t or in any intermediate plane.

The wall 40.,'in.the example illustrated,is cylindrical in iform. lit is obvious that lit might be of any iform of polyhedron, :the cylinder being the ultimate form. It is of .suitable ithickness, which may vvary .as ,the exigencies of the situation demand, and it iis preferably provided with a bottomwsun zfacefll J'beveled vto lcorrespond :to the surface 25 .ofthe .recess Qllin which itrests.
